Operating Temperature, All Package Types
Note: This device contains protection circuitry to guard against damage due to high static voltage or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltage to this high
impedance circuit. For proper operation, Vin and Vout should be constrained to the range Gnd ≤ (Vin or Vout) ≤ Vcc.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either Gnd or Vcc), unused output must be
left open.
